Usagi Electric | Restoring an HP 150A Oscilloscope (Part 1) @UsagiElectric | Uploaded July 2021 | Updated October 2024, 16 hours ago.
So, I headed into town to pick up an old Tektronix scope from a wonderful gentleman, and before I could walk away with the Tek, he mentioned he had an old HP scope hanging about. I got all giddy with excitement and he let me pick the HP up instead!
We may be in over our heads, but it’s such a cool old scope, I can’t give up on it. Let’s see if we can bring it back to life!
